Check iPhone IMEI Blacklist

By using this service, you can get information on Apple iPhone\iPad by IMEI, real country\network provider and SIM lock status (even show if phone has never been activated) and lost\stolen IMEI your phone (Blacklist or no)

This service uses a different Apple server so it is more expensive, and a little longer in time (on weekends may be delayed until then 2 days) than the "Information iPhone by IMEI," but it compares favorably with those that always displays SIM Lock status: Locked \ Unlocked, and always displays operator (carrier) for your smartphone, even if the phone was never activated.
